• Its usage

• Technology oerview

• Database

• Middleware

• Discussion

Maps, Geocoding, Search

Store and query spatial information

SELECT c.holding_company, c.location

FROM competitor c,

bank b

WHERE b.site_id = 1604

AND SDO_WITHIN_DISTANCE(c.location,

b.location,

'distance=2 unit=mile') = 'TRUE'

Store and retrieve geospatial imagery

Store and analyze geospatial networks

Store and manage 3D data

Supports all Geospatial Datatypes

Oracle FMW MapViewer

• Map rendering service: Server component

• Provides a comprehensive set of APIs:

• XML, Java, and AJAX-based

• Enables easy development of client viewers

• Enterprise solution for management of map content and

metadata

• Oracle Maps

• A map cache server

• Caches and serves pre-generated map image tiles for base map layers

• A feature of interest (FOI) server

• Renders dynamic geospatial features on top of base map layers

• An Ajax-based JavaScript mapping client library

• Fetches map tiles and FOI from the server

• Controls user interaction with maps and dynamic features.

• Map Builder

• Utility for creating and managing map metadata

• Create, modify, delete: Styles (colors, text, line, markers), Themes, Map

“Spatial is not special”

• Location is a CORE element of enterprise data

• Location should be openly accessible to the spectrum

of platforms (GIS and non-GIS)

• Location should be a 1st class citizen of enterprise data

management

Try to imagine another core data type being managed

without the benefits of data management ‘best practices’
